The closed beta for Blizzard’s upcoming World of Warcraft vanilla server option launched on May 15th, and Blizzard has now listed some of the apparent issues that the development team is aware of, including class and combat related issues alongside missing textures and more. Blizzard mentions that this list is not a complete depiction of what they’re aware of, but a sampling of issues they believe players may encounter on regular basis.

Start making serious gold with our Crafting section, which will help you determine which items are worth creating by comparing the cost of the materials to the amount they can be sold for. The guides themselves are dynamic, so if you don't already have the recipe required they will tell you how to get it, and if all the ingredients aren't available to buy outright you will have the option to farm them.

One thing they told me when I dabbled into computer science back at university was that 80% of the bugs only take 20% of your time to fix. That's why sometimes you see issues persisting for very long times, not because the devs are lazy or incompetent, but because there is usually a priority list of problems, with the severe-but-easy-to-fix ones always taking precedent and the not-game-breaking-but-difficult-to-solve problems being last line.
But how do you proportionally resize the swing? Even if you did, it wouldn’t give you the same type of joy as when you were a kid, because you have grown up and changed. Even if that wasn’t the case for you, you have to consider that the swing has become a place that is sacred for many other adults. When they visit, they aren’t visiting to try out the new adult-swing. They want to try the old swing. The one that brings back the joyful memories of distant past. They know that the experience isn’t the same, but if they close their eyes ... even for a brief moment ... they just might get that nostalgic thrill that brings them back to a time where things seemed so much simpler.
Swim Speed Potions (used especially at lvl 37 for Faldir's Cove in Arathi Highlands and lvl 57 in WPL).  Try to get multiple stacks of these.  I also recommend keeping a stack of these always in your bags.  You will frequently pass rivers and lakes and can use these potions to pass them faster through out the guide.  Please note that these potions do not stack with Druid's Aquatic Form and Glyph of Aquatic Form.
To get back to Classic for a bit, this is what I think is happening. Players who prefer the old ways (and full disclosure, I'd count myself among them, but to a smaller degree than most) complain/talk about the negative sides of modern WoW and Battle for Azeroth in general. While they do this they also talk about how things were better before and often mention Vanilla as a reference point. People who enjoy BfA now feel attacked by this and so they retaliate. Hence, liking Classic means you either have nostalgia goggles on or have no idea what you're talking about and will hate the same things you say you want 2 weeks after you start playing it. It's an amazing thing, where literally each side is doing to the other what they feel is being (wrongly) done to them. I feel like writing this is the most redundant thing I've ever done, and yet I also feel that it needs to be said, because it seems some people just don't get what they're doing, or at least I hope they don't (some do and are doing it on purpose but there's trolls everywhere so there's no point in even discussing them).
Regardless of the brotherhood shared by the Illidari in their single-minded mission, there is a level of disconnect between Lord Illidan’s demon hunters and the rest of his forces. While this is by no means enforced, it is basically self-imposed by the demon hunters themselves, as the blood elves inhabiting the Grand Promenade had no issue to Vandel spending some of his free time there with their denizens. Furthermore, the bond of brotherhood is not as strong as one might expect between two demon hunters, as during their training and sparring sessions, there is nothing that stops one party from killing another so long as they maintain control of their inner-demons. Just the same, there are those within Illidan’s forces that zealously believe and follow his teachings, mentality, and machinations without question but it is not wholly uncommon for some demon hunters to either question, doubt, or even outright disagree with their lord’s ideals and methods.
2. Your DH needs supplies on a regular basis. They can only carry so much food, clean drink, medical potions and whatever else they want/need at a time. It's pretty realistic that they would need to visit a market every so often, and large faction markets will have the most variety and types of items to choose from. (My DH has been a recluse in the wild for some time, and she is stinky, dirty and has eaten some questionable stuff. This isn't really ideal and a Dalaran doughnut would be pretty flippin nice.)
